Introduction Process of Evaluation This report is the evaluation of the Gumtree website at http://www.gumtree.com.au/ The usability report represents the process of developing an evaluation instrument specifically for the evaluation of the Gumtree at http://www.gumtree.co.au/. The evaluation was directed to determine the quality of the website using the instrument that was made base on HHS guidelines. The data was collected from the website using an evaluation instrument that was developed (see document 1). HHS guidelines and WCAG 2.0 guidelines were used to create a set of criteria for the evaluation instrument (see document 1). The instrument was used to determine and describe data about: * The users of the website * Who are they? * What tasks they need to do? * The Positive and Negative of the website * What can be improved? * What can be maintained? * Is the website trustworthy and safe? * Is the website easy to navigate? * The user experience The quality of the website can be determined after assessing all the data to the criteria drawn from HCI standards and conventions. Some suggestions for improvements are also developed in this report that was based on the instrument data.

Evaluation Evaluation of The Website Background Gumtree is an Australian base website which is designed to connect people as a local classified and community site. Gumtree was officially launched in 2007, which aims to give Australians a simple easy-to-use tool for looking up items that they need. In this report, Gumtree website is being assessed using HCI standards and conventions and furthermore appropriate suggestions can be develop. Some of the evaluations are: User and User Tasks

| | | Type of User | 1 | Buyer - People who are looking for second hand/new items | | 2 | Seller - People who are selling for second hand/new items | | 3 | Job Seeker - People who are looking for job vacancy | | 4 | Job Recruiters - People who are looking for people to work for them | | 5 | Advertisement Brand | | 6 | Government - Watch all the items in Gumtree (not illegal) | | | | User Task | 1 | Buyer | | | Finding the items they are looking for by searching their items in the search bar | | | Finding the items they are looking for from the categories available | | | Contact the seller that are selling the items they are looking for by eMail or Phone | | | Having agreement with the seller about the payment | | | Give the website feedback | | 2 | Seller | | | Putting information about the items that they are selling | | | Putting information about the seller contact information for the user | | | Answering all the questions from the buyer | | | Having agreement with the buyer about the payment | | | Give the website feedback | | 3 | Job Seeker | | | Finding jobs that suits their choice | | | Contacting the job Recruiters | | | Give the website feedback | | 4 | Job Recruiters | | | Putting information of the job they are looking for | | | Answering all the questions from the job seeker | | | Give the website feedback | | 5 | Government | | | Releasing all the regulation | | | Be the watchdog of the website | | | Give the website feedback | The instrument was developed with criteria based on the type of users and the tasks they would do with the website. Below are some of the main problems from the evaluation results:

1. Currency Figure 2 Figure 2 Figure 1 Figure 1
Currency is used to determine the currency of a website or when the page was last updated. It also looks to see if there are broken links, missing links, and expired links (sold items in this case). From the Figure 1, it shows a case where an old advertisement from 2013 is still up while the actual item has been sold although in the term of use, it says that ad duration is 30 days long (some exception occurs) See Figure 2. This shows that the website has not really keeping all ad up to date. Therefore the currency of the website is not really up to date. Although the developer of the website has been keeping up to date with the technology It shows that the layout of the old version of Gumtree is not as great as the newest one (see Figure 3 & 4). It means that the actual website is has always been updated while they have no control of the advertisement, in this case an old advertisement.

2. Consistency Consistency is used to determine how consistent the website in terms of the information in the website and the layout of the website. In this case it was found the inconsistent information in the website. Figure 5 shows that the same advertisement has been released more than one at the same time. Consistency is important for the users, it makes the sites easier to use and in this case the user does not have to scroll down more to look for another ad, while if the same ad has been put up more than one at the same time it will take more time for the users to look for other items. Website should be consistent, in saying that the website should have standards and conventions that should be established and applied throughout the entire website. For example, a user would be having problems if the developer moves the “search” bar for different pages. In this case the layout of the Gumtree website is very consistent as throughout the website has the same layout See Figure 6, 7, and 8.

3. Page Layout The online appearance of the website is an important aspect of the website, and accessibility is a key of the website aesthetics that has to be integrated. Proper layout makes the website more appealing to the customers. The primary role of web design is the layout of the website because the layout creates the website to be attractive and in some cases the website that does not have graphics can be attractive if they have a good layout design. Assessing Gumtree layout, it is very attractive and it has very consistent layout throughout the website. The website has to maintain this great layout consistency and attractiveness in order to keep the user interested in the website. The Gumtree website has moderate white space of the side of the page (See Figure 9) which is good to improve website readability and website performance. White space is also an important aspect of the website design and Gumtree has done well in order to improve website readability. Although Gumtree has a good understanding of the web design purpose, it was found a small problem in the website. Figure 10 shows that when the size of the browser is resized to be half size, the logo and the help title page are on top of each other which causes decrease of website readability. Therefore by fixing the problem it would help the website to be even better in terms of website readability.

4. Security Customer is concerned with the security of the website. For a business website such as Gumtree, eBay, and etc. the security of the website is the number one reason for customer to shop/use that particular website, in saying that making sure that the website is doing all they can to ensure and provide a safe site for the customers and user is essential. Assessing Gumtree level of safety, Gumtree is not a safe website for the user to put their information as seen in Figure 11, that anyone can see seller’s contact details. This causes the high number of spammers that can defraud the seller. Although Gumtree help page releases some articles about avoiding all the spammers, in this case that is not the answer to this problem. One suggestion would be by not letting random people to get seller’s information, in order to get the seller’s information users have to log in to their account to get the seller’s information and the website could track the people that get the seller information. Therefore the website could track down for any defraud transaction.

Instrument The Quality of the Instrument The instrument that was implemented in Document 1 was developed in correspondence to the guidelines and regulations of the HCI model. HHS guidelines and WCAG 2.0 guidelines was used to create a set of criteria for the evaluation instrument (see document 1). The quality of the instrument that was used to assess the Gumtree website determines the final result of this report. The quality of the instrument that was used to evaluate Gumtree website was basic, simple and served its purpose. The purpose of the instrument that was develop was to rate the quality of Gumtree website using a criteria that would be important to the users. The instrument was broken into different section of criteria. 1. Design Process and Evaluation Design process and evaluation was used to assess the website to find out some of the process and evaluation of the website such as “does the website has set and state goals?” Basically this criteria focus on the process of the making/upgrading of the website then evaluate what has been changed, improved, and implemented. From the evaluation, the website will know the result of the changes that has been done, therefore the website can keep improving. This is good for the website to check whether the changes that has been done is efficient or better than the version before or it makes the version worse than the version before. This process would be repeated for many of times to find out the best answer of the problem that website had before. 2. Optimizing The User Experience A good user experience is essential to a successful internet marketing strategy. For a business website, Gumtree has to keep testing and refining that experience can help significantly increase conversions and drive sales. User experience involves balancing the needs for users with the business objectives and resolving any conflict between the two. In this case, it was found that Gumtree has some points that is not good for the user experience, such as not providing the user with printing options and not giving the users the warn of the ‘Time Out’. However, Gumtree has done well with some other aspects of the user experience for example providing assistance to user, providing feedback from user for better user experience, and not displaying unsolicited windows or graphics. Therefore the user experience criteria for assessing a website is an important aspect and is crucial to a successfulness of the website. 3. Accessibility Web accessibility means that people with disabilities can comprehend, use, and interact with website, therefore they would be able to contribute to the web. We accessibility criteria is important because in order to provide equal access and equal opportunity to people with disabilities, it is essential that the web is accessible for them. Therefore using this criteria to assess Gumtree can find whether Gumtree website is accessible for people with disabilities. 4. Currency Currency of a website suggests to how current or up to date the website is. Many website states the last update or modify in their page and it is usually visibly at the bottom of the page. Currency is important, as the user cannot really rely on any information contained on the website where the currency of the information of the website is not stated or cannot be verified. Because a website that regularly maintain and update is much more likely to contain more accurate information than the one that is not well maintained. 5. Page layout
Page layout is one of the most important things that need to be consider when thinking about making the website. That is because the website the users will judge the website by the design and content. The layout of the page should be consistent and logical. The types of users should be able to understand the structure of the page and why relevant information is where it is.

6. Navigation
Navigation is one of the most important elements of website design. If a website is lacking in effective navigation, it is not working the way the business wants it to be. One of the example would be well organizing the website, because it helps the site visitors find what they need, with as little effort as possible. The users should be able to navigate through the site naturally without having to adjust the browsing habits to suit the website. The criteria in the instrument outline the types of expectations users may have. 7. Consistency Consistency of any website is one of the key sings of website is developed or designed by professional. Ensuring the website is consistent throughout the pages gives the website a unified feel, improving the user experience and increasing the conversion rates. Consistency of a website is not just about the consistency of the color scheme or similar set of fonts, it also focuses on the website behavior is consistent. 8. Security Website security where the users feel safe is vital to the website’s success. In recent times, cyber crime has shaken up the world’s largest organization. The security of the website also determine the site reputation, and why risk damaging the site reputation when maintaining website is very simple and effective. There are some tools already develop to prevent any cyber crime. Therefore this criteria was chosen to assess the Gumtree website. Conclusion The instrument was an effective tool in evaluating and assessing Gumtree website. Gumtree needed some improvement its security dramatically, based on the results. The seller’s contact details are supposed to be safe from cyber crime. There are some other aspects that can be improved from the Gumtree website, and by improving all the problems can result in attracting more users and drive up sales of the site.

Usability

...Usability When using a website, it is important that it is as simple to use as possible. Users are impatient and want to access the information on the website as quickly as possible without having to think of where to click to access this information. Users don’t read the whole content of the page, they scan it. It is therefore essential to design the web page with this in mind, therefore writing important information in bold and writing short, to the point headings. As illustrated in the figure below, this is what we have tried to convey on our website. We made sure we had the main point in bold and a bigger font. In regards to the five e’s efficient, effective, engaging, error tolerant and easy to learn, we believe we met these five characteristics. Especially in terms of it being efficient and engaging. Our website is efficient because the logo on the top left corner is linked to homepage on every page. This makes it easier for users to navigate back to where they started with the minimum amount of clicks possible. Our website is particularly engaging because we paid a lot of attention to the presentation of it to make it aesthetically pleasing to the user. The users immediate reaction to design and readability can change their relationship with the website and weather they would want to use it or not. One of the things we did to make our users of the website engage more was through the use of white space. In order for it to not come across as too cramped......

Usability Assignment on Web Accessibility

...Usability Assignment on Web Accessibility Wendell Robinson Capella University Web Accessibility Initiative's Accessible Rich Internet Applications (WAI-ARIA) need to be the concern of all web developer. Many people like myself can’t imagine their life without the internet it is where we get our world and local news, email, entertainment, etc. If a developer makes his website to be more accessible he ensure that people with disabilities can access his website just everyone else. The people who are visually impaired could access their content with the help of a “screen reader”. Screen reader applications read the printed text out loud, which helps blind people use computers and receive access to a text content of any kind. The blind can just open up a browser and listen to a screen-reader The physically impaired people can get the access to online content with the help of their computer using technologies that were designed to adapt the computer interface to their disabilities. People who are hard of hearing have always had the opportunity to read online content, however when it comes to video materials, they can read typed versions of important speeches or watch multimedia content with subtitles. One reason accessibility is important is that it can increase your audience. Without accessibility there is bound to be people in your audience who are not able to see, hear or simply pick up the mouse to navigate your website. This could mean loss of profit......

Web Usability Analysis Project

...Web Usability Analysis Project Philip Mambo Capella University Introduction Usability is how easy an object is to use. The object can be almost anything, including a machine, tool, process, book, software application or website. Anything that a person can interact with should be usable. In the case of websites and software applications, usability has been defined as the ease at which an average person can use the software or website to achieve specific goals. Usability is comprised of learnability, memorability, efficiency, satisfaction and errors. Learnability is how easy it is for a new user to accomplish tasks the first time they visit your website. Memorability is how easy it is for someone to come back to using your website after they haven’t used it for a period of time. Efficiency is how quickly users can complete tasks on your site after they are familiar with its use. Satisfaction is whether users enjoy the design of your site and errors refers to the number of errors users make when they use your site, the severity of the errors and how easy they are to recover from.

Analyzing Results of Usability Testing

...Analyzing the results of Usability Testing By Ben Homrig and Justin Stephenson For our presentation, we were assigned with analyzing the results of usability testing. Usability is defined as the process or technique used to interactively test and assess the user-interface of a product, method or set of instructions. Presenting and analyzing data are very important steps in process. The improvements developers and technical writers make with their data define exactly how the end product will be when completed. Understanding the differences in the types of data tabulated is vital to understanding how results are analyzed. In usability testing, there are two types of data – qualitative and quantitative. Quantitative research must measure the products in an objective, quantitative and statistically valid way. This type of data recorded must be hard evidence, free of context and exact. Qualitative data is collecting, analyzing and interpreting data by observing how people respond through their opinions and actions. Data is generally collected through gathering information from focus groups and in-depth interviews with users. Quantitative research is defined as objective, while qualitative is subjective. The differences between qualitative and quantitative data are very important in improving a product, method or set of instructions. In our case, we established our primary example as that of a tester documenting the experience a user has while trying out a new iPhone game......

Paid Website Usability Testers

...Paid Website Usability Testers Kazi Ziaul Islam Strayer University Human Computer Interaction CIS375 Prof. Kourosh Samia December 8, 2014 Paid Website Usability Testers Two attributes determine if a website is useful and they are usability and utility. Utility is whether or not the website provides the required information or features. Whereas, “usability is a quality attribute that assesses how easy user interfaces are to use.” (Nielsen, 2012, para. 1) You cannot have one without the other. Suppose your site is brimming to the top with lots of information and has all the bells and whistles, but if the Interface design (ID) is poor and as a result the User Experience (UX) suffers then no one is ever going to spend the time and effort to discover those great features. This is the main reason why companies must perform usability evaluation. Although the heuristic evaluation method may take less time and is usually less expensive, the “heuristic evaluators could not play the role of real users and could not predict actual problems users might face while interacting with the sites” (Hasan, Morris, & Proberts, 2012, p. 726) User Testing is essential prior to going live in a production environment and can done on a budget. Katie Sherwin of the Nielsen Norman Group reiterates that “testing doesn’t have to be expensive and by testing with just 5 users, you can uncover 85% of the issues.” (Sherwin, 2014, para. 8) After all it is an iterative process and the law...

Usability of Ipads and Websites

...Usability of iPads and Websites Name Professor Course Date The tablet market is growing at a high rate, the iPad being the best selling in this segment. The iPad has many uses such as; streaming videos, playing games and surfing the internet. However its usability has come under critics from several parties. The purpose of this research is to evaluate the usability of the iPad from a consumer stand point. In 2011, the Nielsen Norman conducted a research on the usability of the iPad, and published a report. A total of 26 apps and 6 websites were tested. Many apps which the participants had installed on their iPads were also tested. Sixteen users participated in the research who were evenly distributed in terms of gender. Their average age ranged between 21 years and 50 years. The tests included; the usage of gestures, implementation of the back buttons, and the organization of the app or website. The findings of the tests were; usage of splash screens in websites and apps, squeezing of information into very small areas, making it hard to recognize, usage of excessive navigation methods and over usage of the swipe gesture in the apps. Despite the efforts being made by the developers to make iPad apps and websites more usable, there is still a large room for improvement as indicated by the test findings. The use of gestures is an inconsistent interaction design as described by Nielsen. The user interface differing from app to app is the most frequent inconsistency......

Usability Evaluation

...Usability Evaluation Professor Cox CIS 375 Abstract Online surveys are a great alternative to lavish mail or telephone surveys. There are a few requirements to online surveys however that you must be aware of. Using the Internet to conduct quantitative research presents challenges not found in conventional research. Some of our knowledge concerning the effective design and use of paper-based surveys does translate into electronic formats. However, electronic surveys have distinctive technological, demographic and response characteristics that affect how they should be designed, when they can be used and how they can be implemented. Survey design, subject privacy and confidentiality, sampling and subject solicitation, distribution methods and response rates and survey piloting are critical methodological components that must be addressed in order to conduct sound online research. The easy and difficult aspects of creating and conducting an online questionnaire are a constraint, timeliness, important and the nature of the research requires it. While there are three types of questions have numerous versions. eSurveysPro, for example, offers a dozen different question types based on these three basic types. For example, you can have a multiple choice question that lets the customer choose from a dropdown list, a vertical (up/down) list of choices, or horizontal (left/right) choices. This may seem cosmetic but dropdown lists might delay participation because the......

...15 Assignment 3: Usability Evaluation 15 Assignment 3: Usability Evaluation Questionnaire is one of the most popular techniques for gathering data, where questions in a questionnaire are designed to be answered asynchronously, i.e. without the presence of the investigator. A goal must be set, before developing the questionnaire, as developer would like to have relevant reasons before starting working on something. Targeting the participants is another important element of collecting data through online questionnaire. In many ways questionnaire is similar to interviews as questions could be open or closed. Since interviewer is not present or in a word nobody is available to interpret the questions for the participant, making the questions clear and data collection efficient -- questions need to be clearly worded. Skilled people are needed to design a questionnaire especially to gather valid and reliable data. Easy and difficult aspects of creating and conducting an online questionnaire: First, I would explain the easy aspects of creating and conducting an online questionnaire. Online questionnaire is very effective when targeting a large number of people in terms of gathering valuable information. There are two ways of doing online questionnaire: email questionnaire and web based questionnaire. Email questionnaire is not that effective and hard to reach a maximum number of participants. On the other hand web-based questionnaire can reach any region in the world...

Usability and Security

...Running Head: USABLE SECURITY THE IMPLEMENTATION Usable Security the Implementation Name Institution Abstract This project was about usability security and its implementation. It involved the designing and development of a suitable human computer interface to provide a log on module for the Kuwait armed forces computer system. The development focused on relieving the user from the load of creating, remembering and maintaining their passwords for the login process. Based on the fact that the Kuwait information and communication technology literacy levels are still in their infancy stage, the conventional authentication system was proved unfriendly to the user. This system was developed with this in mind. This proposed system relies on the user logging in to the system after identifying five pictures they uploaded earlier from among a grid of twenty five pictures. By selecting the five correct pictures which they uploaded, the system was able to successfully authenticate the user. Using these pictures greatly reduced the mental load on a user who was required to remember strong passwords that ended up being compromised (Badre 2002). The use of pictures or graphical images for authentication or access control is a practice called biometrics that is gaining popularity in establishing system security today. Due to the need to deliver a solution in the shortest time possible the...

Usability Testing

...Usability testing is a technique used in user-centered interaction design to evaluate a product by testing it on users. This can be seen as an irreplaceable usability practice, since it gives direct input on how real users use the system.[1] This is in contrast with usability inspection methods where experts use different methods to evaluate a user interface without involving users. Usability testing focuses on measuring a human-made product's capacity to meet its intended purpose. Examples of products that commonly benefit from usability testing are foods, consumer products, web sites or web applications, computer interfaces, documents, and devices. Usability testing measures the usability, or ease of use, of a specific object or set of objects, whereas general human-computer interaction studies attempt to formulate universal principles. History of usability testing Henry Dreyfuss in the late 1940s contracted to design the state rooms for the twin ocean liners "Independence" and "Constitution." He built eight prototype staterooms and installed them in a warehouse. He then brought in a series of travelers to "live" in the rooms for a short time, bringing with them all items they would normally take when cruising. His people were able to discover over time, for example, if there was space for large steamer trunks, if light switches needed to be added beside the beds to prevent injury, etc., before hundreds of state rooms had been built into the ship.[2] A Xerox......
